ARTHUR A. JOHNSON. or NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS.TO UNDERWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OFDELAWARE.

TYPEWRITING MACHINE.

Application filed August 15, 1918.

T 0 aZZ whom it may concern:

Be it known that I, ARTHUR A. JOHNSON, a citizen of the United States,and a resident of the city of New York, county of the Bronx, and Stateof New York, have invented an Improvement in Typewriting hlachines, ofwhich the following is a specifica-.

tion.

This invention relates to typewriting machines and more particularly tomargin-dedesired column while returning it to begin a new line, andreadily determine what key or lever to operatelin selecting a columnwithout numbers or other designations. According to the presentinvention the parts are so arranged that the operator simply points hisfinger, as it were, at the column to be selected and operates the levernext to his finger; to set a margin-determining stop for arrestingthe'carriage at the selected position, these manually operablestop-setting members or levers being adjustable along the front of thecarriage to the different column or paragraph locations.

The specific mechanism of the present disclosure comprises upstandinglevers which are. in many respects, similar to the linespace lever ofthe Underwood typewriting machine. These upstanding levers are arrangedin front of the work-sheet and when located in proper positions aredirectly in front of the columns at which the typewriter carriage willbe respectively arrested by them. In addition to returning and arrestingthe typewriter carriage these keys also perform the line-space operationfor the ma-- chine. That is, they are connected to linespace mechanismso that when operated the Specification of Letters Patent.

line-space mechanism from.

Therefore. apart from its other functions. each of these stop-settingkeys or levers may be'considered as a manually operable line-- spacingmember.

My device as illustrated in the accompanying drawings, has furtheradvantages. This structure comprises a rack slidably mounted upon atypewriter carriage at the front thereof. Adjustable along this rack Ipro vide my stop mechanisms, each stop mechan sm or stop devicecomprising a member to which the lever is pivoted and also carrying astop member. The arrangement is such that when the lever is operated thestop member is swung upon the rack into engagement with a part of acooperating member or second rack on the carriage frame. For the purposeof permitting the first rack to effect operations, a lost motionconnection is provided between this rack and the second rack on thecarriage frame.

Another advantage of the present disclosure is the simplicity of thedevice and the ease with which the device may be attached to thetypewriting machine.

Other features and advantages will hereinafter appear.

In the accompanying drawings,.

Figure 1 is a perspective view of my invention applied to thetypewriting machine.

Figure 2 is a side elevation of my device showing the typewriter platenand the print ing type.

Figure 3 is a rear elevation showing the parts in normal position.

Figure 4 is a rear elevation showing the lever swung to set the stop butnot operated to return the carriage and line-space the platen.

Figure 5 is a rear elevation showing the lever operated and thetypewriter carriage arrested by means of the stop, the line-spaceoperation having been performed by this time. I

In the Underwood typewriting machine a platen 10 is carried by aframe11, on carriage 12, to receive the printing impressions is operatedtherefrom types 13, which strike upwardly and rearwardly against theface of the platen. The typewriter carriage 12 is moved in letter feeddirection by means of the usual escapement mechanism and the platen 10receives rotary movements for line-spacing from a line-space devicecomprising a handle 13 pivoted to the carriage frame at 1 1, and havingan arm 15, which engages a slide 16, having the usual pawl whichcooperates with a ratchet wheel 17. The platen may be also rotated bymeans of the usual knob 18. The typewriting machine frame comprises sidemembers 19 and 20, joined by a connecting piece 21, which carries theusual letter space scale, not shown.

The device of the present disclosure comprises a supportng bar 22. whichhas hooks 23, gripping a bar 2 1, which forms a front tie rod of thecarriage. This supporting bar 22 may be made of malleable material sothat the hooks 23 can be bent around the transverse front bar 24, inattaching same. slid abl mounted upon the supporting member or Jar 22 Iprovide a rack 25, having teeth 26, and grooves 27 The rack .25 is heldto the supporting member 22 by means of a screw 28 threaded into themember 22 and passing through an Ad ustelongated slot 28 in the rackably mounted upon the slide or rack 25 is a plurality of stop-carryingmembers 29, which slide in the grooves 27'and carry levers 30 and stops31. Each stop-carrying member 29 is adjustably held. in position on therack 23 by means of a detent 32, engaging the teeth 26, thereon. Thesliding lever 30 is pivoted at 33, and has a depending arm 34 forengaging its stop member 31. Then the operating member 30 is actuatedpreparatory to returning the carriage. its depending arm 34 engages withthe stop member 31. which is held up in normal position by a spring 35,and causes an engaging portion or stop lug 3(8 to be moved into linewith a cooperating stop or lug 37 secured to a rod 38. which is mountedupon the side mem hers 19 and 20. The operator then moves his arm toreturn the carriage. \Vhen the stop member 31 is moved to operativeposition, a locking tooth 39 on the stop 31 engages in a rack 40,carried by the supporting member 22, so as to be substantially connectedto the member 22. \Vhen the carriage is returned, it is often the casethat the linespace operation does not take place until after the usualarresting lug on the carriage strikes the usual arresting lug on themachine trame. Therefore, l. have arranged my mecl'ianism so that thiscan also be the case with my device. For this purpose I have provided apin and slot connection between the stop 31 and the stop-carrying member29. This comprises a pin 41 on the stop; carrying member rining in aslot 4-2 in the stop 31. Drawing a. handle or lever 30 to the right atFigure 1 returns the carriage, and the line-si'iace operation iseffected by means of a hooked portion 42 overlying the line-space lever13 and secured at 43 to the sliding member 25, so that the movement ofthe slide to the Figure 5 osition actuates the line-space lever 13. twill be noted that the stop-setting lever 30 forms a linespacing memberwhich efi'ects line-spacing concomitantly with the return of thecarriage 12 to a position determined by the adjustment of the stopmember 31.

As has heretofore been said, this linespacing movement of the slide 25may take place at the beginning or at the end of the operation,according to the amount of friction of the various parts. When thecarriage is returned, the parts reach the Figure 5 position in which thestop 36 engages stop 37, on the machine frame.

Thus, it will be seen, that the stop 31,

while connected to the movable slide 25,'is

nevertheless directly connected to the carriage durin the operationthereof. The slot- 42 in he stop 31 permits this, While, on release ofthe lever 30,- a spring 44 draws the stop 31 back along the the springis fast. It will be noted that the operating levers 30 are connected tothe typewriting machine so as to extend directly in front of theWorksheets carried by the platen, and in practice these stops will beadjusted according to the stop places desired on the worksheet, asillustrated-on the accompanying drawings. Thus, it is only necessary forthe operator to pointhis fingers at the predeterminechplaceat which hewishes the carriage to be arrestedand oprate the lever 30 directly infront of this.

It is to be noted that each of the levers 3U has a four-fold function.First, by its position along the front of the carriage it indicates onthe work-sheet the column or paragraph at which writing is to beginsecond, by pivotal movement on the screw 33 it. sets or makes effectivethe margin determining or paragraphing stop 31; third, by impartingmovement to the slide orrack-bar 25 1t line-spaces the platen 10; andfourth. by movement transmltted from the slide 25 to the carriage '12 itreurns the carriage to the selected position determined by the stop 31.A single push against the lever 3 accomplishes all of the operationsHaving now 'described my invention T.
